current split between neutral and earth
current split between neutral and earth
(OP)
On an overhead 4-wire multigrounded neutral distribution system, how much current is typically assumed to split between neutral and earth?
We typically assume a 50 - 50 split and use this result for voltage drop and fault calculations. I was just wondering if this was commonly followed.

For voltage drop studies, you usually use the sequence impedances in a sequence phase impedance matrix rather than using a split between ground and neutral currents.

Abstract
Starting with a modified version of Carson's equations, this paper develops distribution feeder models that can be used in the power flow and short circuit analysis of unbalanced three-phase distribution feeders. A simple line section is used to demonstrate the differences in voltage drops that occur between the various models for load conditions varying from balanced to very unbalanced
